While various factors contribute to the severity of acne vulgaris, recent studies are progressively studying the interesting relationship between acne vulgaris and eating habits. Scientific studies have found that certain eating habits such as foods with high fat and glycemic index, products containing milk and energy-dense, and high-calorie foods play a role in exacerbating acne vulgaris. This study aims to determine whether there is a significant relationship between eating habits and the severity of acne vulgaris in grade III and IV students of the Faculty of Nursing, Universitas Klabat.This research is a quantitative research with a descriptive correlation method through a cross-sectional approach. The research sample was taken using a total sampling technique with a total of 205 respondents. Data was collected using the Adolescent Food Habits Checklist (AFHC) questionnaire to measure eating habits, and the Global Acne Grading System (GAGS) to measure the severity of Acne Vulgaris. It was found that most of the students were in the category of poor eating habits, with a total of 114 (55.6%) respondents, and had mild acne vulgaris, with a total 109 (53.2%) respondents. After conducting bivariate analysis using the Spearman's Rho, it was found that the value of p = 0.001; and r=-0.646. There is a significant relationship between eating habits and the severity of acne vulgaris in grade III and IV students of the Faculty of Nursing, Universitas Klabat. The level of coefficient correlation was classified as strong with the negative direction, where the poorer respondent's eating habits are, the higher the severity of acne vulgaris. It is recommended for the students to pay attention to their eating habits by reducing foods high in fat, calories and glycemic index, and starting to eat fruits and vegetables regularly. For further researchers, it is possible to measure the comparison of certain types of food as well as the schedule, and number of food portions consumed and their effect on the severity of acne vulgaris.
